Well, first of all hamsters aren't supposed to be living in the same cage with other hamsters (unless dwarf) so what makes you think that a hamster can like a turtle.

And hamsters are vicious little animals. Hamsters DO NOT like turtles.
Hamsters eat anything from curry to ice cream. They eat anything, trust me. Hamsters may like or not like mushrooms.
It's like a ball of yarn for the cat to play with.
